Abstract

PROBLEM TO BE SOLVED: To facilitate registration and loopback transmission by registering a telephone number automatically to an electronic telephone directory. SOLUTION: A control section 9 recognizes a caller telephone number via a lie interface circuit 4 at the arrival of a call from a caller telephone number notice service line 2 and reads time data at the arrival of a call from a system clock 6 simultaneously and stores the caller telephone number and the time data to a caller telephone number storage means 8. A name is added to the caller telephone number stored in the caller telephone number storage means 8 by the registration to register the name to an electronic telephone directory 7 automatically just before a speech by a telephone set 3 at the end of call. Even when a caller name or an enterprise name is not registered at the end of call, the caller telephone number storage means 8 retrieves a caller telephone number by using the time data as a parameter to make loopback talking.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange capable of utilizing a caller telephone number notification service.

[0002]

2. Description of the Related Art Conventionally, in order to create an electronic telephone directory in a private branch exchange, it was necessary to check the name and telephone number of the other party and register both of them in a memory inside the private branch exchange.

Further, conventionally, when the user makes a call back, it is necessary to check the telephone number of the other party to make the call.

[0004]

However, if the name of the other party is known but the telephone number is not known, the other party's telephone number must be checked in order to create an electronic telephone directory, and even during registration. Since it was necessary to register the other party's name and telephone number, there was a risk of making a typo.

Further, when making a call back, it is necessary to check the telephone number of the other party before making the call, which is troublesome.

The present invention solves such a conventional problem and improves the operability of the user by automatically making an electronic telephone directory by utilizing the caller number notification service. With the aim of providing an electronic exchange that enables accurate input, the caller ID notification service is used to store the telephone number of an incoming call as a parameter, It is an object of the present invention to provide an electronic exchange that can easily make a call and improve the operability of the user.

[0007]

Means for Solving the Problems The technical means of the present invention for achieving the above object is a storage means capable of storing a caller's telephone number when an incoming call is received by utilizing a caller telephone number notification service. An electronic telephone directory is provided which allows a user to add a name to the above-mentioned telephone number and register it by performing a name registration operation from a communication terminal at the end of a call.

Another technical means of the present invention for achieving the above object is to use a caller telephone number notification service and to provide a storage means for storing the caller's telephone number with a time as a parameter at the time of an incoming call. The terminal is configured to be capable of making a call back by performing an input operation using time as a parameter.

[0009]

According to the present invention configured as described above, if there is an incoming call, it is possible to register in the electronic telephone directory, so that the time and effort required for creating the electronic telephone directory can be greatly reduced and the telephone number cannot be known. It is not necessary to check the telephone number when registering the other party in the electronic telephone directory, and the maintenance of the electronic telephone directory can be simplified.

Also, if you only remember the time of arrival,
It is possible to call back without checking the telephone number of the other party.

[0011]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 1 is an electronic private branch exchange, 2 is a caller ID notification service line, and 3 is an extension telephone. The electronic private branch exchange 1 includes a line interface circuit 4, an extension interface circuit 5, a system clock 6, an electronic telephone directory 7, a caller telephone number storage means 8, and a control unit 9 for controlling the entire electronic private branch exchange 1.

The above configuration will be described in more detail below together with the electronic telephone directory creating operation.

First, when an incoming call arrives via the caller number notification service line 2, the control unit 9 recognizes the caller's telephone number via the line interface circuit 4 and temporarily stores it in the caller telephone number storage means 8. store.

After the end of the call, the user performs a registration operation such as inputting the name (personal name, company name, etc.) of the other party from the telephone 3, and the other party stored in the sender telephone number storage means 8 The name of the other party can be added to the telephone number and registered in the electronic telephone directory 7.

If this operation is not performed for a certain time at the end of the call, the telephone number stored in the sender telephone number storage means 8 is discarded.

Next, the return transmission operation will be described.
First, when an incoming call is received via the caller number notification line 2, the control unit 9 recognizes the caller's telephone number via the line interface circuit 4, and the caller is read along with the time of the incoming call read from the system clock 6. Stored in the telephone number storage means 8.

After the end of the call, the user inputs the time of the incoming call from the telephone 3, and the control unit 9 retrieves the caller telephone number from the caller telephone number storage means 8 using the time data as a parameter. It is possible to make a call back to the other party who has received an incoming call through the line interface circuit 4.

Although the electronic telephone directory creation and the return call are described in one embodiment of FIG. 1, the electronic private branch exchange 1 is provided with only the functions necessary for each operation and can be configured as separate embodiments. Yes, both operations can be used together.

[0020]

As described above, according to the present invention, by using the caller number notification service, the operation of creating an electronic telephone directory can be performed easily and accurately, and the operability of the user is improved. Can be improved.

Also, using the caller ID notification service,
By storing the telephone number of the caller together with the arrival time, it becomes possible to easily make a return call.
